1. Tutorial
Exercise 1. Read the text and tell the picture about ionospheric
correction algorithm.
NeQuick is a semi-empirical model that describes spatial and temporal
variations of the ionospheric electron density.
NeQuick (Fortran 77) source code is only available in its 1994 version.
All of the models
are able to create
electron density
profiles, but among
them NeQuick is a
flexible quick-run
model that has been
proposed for single-
frequency operation in
the Galileo project to
compute the slant total
electron content along
arbitrary ground-to-
satellite ray paths.
Exercise 2. Select the correct statements. Use the text ex. 1.
1. NeQuick model is a empirical model.
2. In real-time application of NeQuick for the future Galileo
navigation system.
3. NeQuick model developed in FORTRAN 77.
4. In real-time application of NeQuick for the future GLONASS-
K navigation system.
5. NeQuick model is a semi-empirical model.
6. NeQuick model developed in C++.
